Add libcamera V4L2 compatibility layer.
This initial implementation supports the minimal set of V4L2 operations,
which allows getting, setting, and enumerating formats, and streaming
frames from a video device. Some data about the wrapped V4L2 video
device are hardcoded.
Add a build option named 'v4l2' and adjust the build system to
selectively compile the V4L2 compatibility layer.
For now we match the V4L2 device node to a libcamera camera based on a
devnum that a pipeline handler may optionally map to a libcamera
camera.

The 'tests' option enables compilation of tests. On Gentoo and Chrome
OS, the corresponding package USE flag is named 'test'. Rename the
option to 'test' to bring it in line.

Add libcamera Android Camera HALv3 implementation.
The initial camera HAL implementation supports the LIMITED hardware
level and uses statically defined metadata and camera characteristics.
Add a build option named 'android' and adjust the build system to
selectively compile the Android camera HAL and link it against the
required Android libraries.

Re-order the project options and add documentation which will be
presented by 'meson configure'.
This produces the following extra information:
Project options:
Option Current Value Possible Values Description
------ ------------- --------------- -----------
documentation true [true, false] Generate the project documentation
tests true [true, false] Compile and include the tests

It can be desirable to disable the compilation and processing of both
the test suite and documentation for use cases such as packaging to an
embedded target.
Provide a new meson_options.txt file to allow disabling either or both
of the tests and documentation components of libcamera.
These options can be provided at the initial configuration time, for
example:
meson build -Dtests=false -Ddocumentation=false
or by reconfiguring an existing build tree:
cd build
meson configure -Ddocumentation=false
meson configure -Dtests=false
